I recently changed my sparkplugs on my 2014 Roush Raptor. After which I threw a bunch of codes but got most of them resolved (P115E; P2098; P219B). I got the throttle body cleaned and found that the original shop that installed the plugs left a vacuum hose disconnected which got reconnected when the throttle body was cleaned. The code that is sticking around is p219B and its killing me. I have changed all the plugs to what JDM suggests the NGK 6510 at .030 I then changed both bank 2's front and back o2 sensors, then I replaced the fuel injectors. When the injectors got replaced we noticed an exhaust leak but they tightened the manifold on bank 2 side and that went away you cannot hear the exhaust leak on start up anymore. I am still getting this this P219B code the only symptom I am getting that I have noticed is after driving when I put the truck in park the idle tries to find itself (RPM needle dances) for a bit then it levels off. The only other thing I somewhat notice is that I can hear a whistle sometimes its very faint and it makes me think vacuum leak but where. Any help would be greatly appreciated as I feel I am just dumping money into this thing in all the wrong places.
